So let me get this straight. We open a terminal window, run through a bunch of commands, and the system pretty much hangs, waiting, because we have not set the port at 30000. To do so, we have to open a DIFFERENT window, somehow go through the process again (it’s not clear, the presenter zipped straight into the new commands without clarifying the setup), run through a bunch of commands that (don’t actually) reset the port to 30000, and then shut DOWN the original window from the second window? Do I have this right?
What kind of weird workflow is this? Open a window, open another window, set parameters from the second window, close the first window?
Why not just write your code so that you can set a port from within the first window? This is the first time I ever saw a command line interface that didn’t let me set a basic configuration like port directly from the CLI.
